And in a button or in onClick event of a field:
show_calendar(‘document.forms[0].MyDateField.value’)
Change ‘MyDateField’ to the name of the field where You would like to have the date stored. Remember that the field must be editable and present on the form. You can hide it by setting the HTML properties: Type=hidden. This will cause the field to be hidden, but visible in the sourcecode.
